T0 all whom z'zfi may conoem:

Be itknown that we, CHARLES J. BOHRER and CHARLES E. NACHIRAB, residing at Toledo, Ohio, citizens of the United' States, have invented certain new and useful Improvements in Internal-Combustion Engines, of Which the following is a specification.

The object of our invention is to utilize to the fullest extent possible the energy of gasolne used in internal combustion engines and to do so by a device or instrumentality of extremely simple construction and not easily put out of order. Our invention is'applicable to motors using gasoline or liquid fuel that is vaporized regardless of the use that is made by the poWer produced by the motor, whether for automobile, tractor, air plane, etc. Our invention consists in whatever is defined by or included within the terms or meaning of the appended claims.

In the annexed drawings: 4

Fig. 1 is a view in longitudinal section of one embodiment of our invention;

Fig. 2 is a section on the line 22 of Fig. 1;

F ig. 3 is a detail view in perspective of the rotary, gas-engaging device.

Briefiy described our invention is embodied in a rotary device situated in the path of the gas on its way to the motor so that before the gas enters the engine cylinder it Will corne in contact With such device, and by rotation of the latter produced by the flowing current of gas, the gas Will be agitated and so stirred up that it Will be so highl vaporized by the time it reaches the cylinder that practicallv complete combustion Will take place Within the' cylinder, and the power of the gas utilized t0 a liigh degree.

Describing in detail what is shown in the drawings, we place Within a cylinder, 10, of suitable metal a shaft, 11, at the conter thereof, Which is supported and journalled in a diametrically extending crossbar, 12, the shaft having on opposite sides of the cross-bar, collars, 13, that restrain endwise movement of the shaft, the cross-bar 12, being located at substantially midlength of the cylinder 10. Upon the end of the shaft towards the inflowing stream of vapor is a fan, 14, composed of any desired number of blades or vanes set at such an angle that the gas passing over the sides of the vanes Will cause the revolution of the fan and shaft, and at the other end of the shaft there are several radial blades or arms. 15, which by the revolution 01: the shaft beat or strike against the gas flowing through the cylinder, 10, and impart a whirling and stirring motion thereto that produces or causes vaporization thereof to a high de2'ree. The gasoline flowing between the vanes of the an is subdivided into numerous small streams and is thereby prepared for the action of the agitating or stirring device. Preferably the arms of the stirring or agitating device are concavo-convex and they revolve with the concave sides forward.

By our invention not only is great saving of gas effected, but With a car having its motor equipped With our invention, the motor can be idled down to a lower speed than can the same motor without it and the motor Will run more evenly.

lVe do not restrict ourselves to any one size of device nor to the application of our invention to any particular style or kind of motor, nor to the number of cross bars for supporting the shaft for one or more may be used, n01 to any of the details of construction shown in the drawing.

Merely to illustrate one installation we show in the drawing the device applied to the intake, 16, of a manifold just beyond the carbureter. The diameter of the cylinder, 10, is substantially that of the interior of the intake and at its outer end the cylinder has an outwardly projecting flange, 17, which lies between the carbureter attaching flange, and the intake fiange and thereby our said device is securely and yet Withont any special attaching means held in place. VVhen the carbureter is already in place it is necessary merely to remove it for the insertion of our device into the intake and then to replace the carbureter. When applied our device is invisible and so protected that it can not be tampered with or injured.

A very important advantage from placing our device within the manifold, or beyond the carbureter, is that no disturbance of the usual position of the carbureter is caused such as throwing it further away from the engine or disturbing its proper alinement, which results from the interposition of such a device between the manifold fiange and the carbureter. Another important advantage is that the manifold becomes efiectth o'ffc1ri so that nothmg in the nature ot a cas1ng 1s required beyond the simple cylindi '10,"'
